Fair Use

Some videos on this website include stills and short clips from motion pictures, which belong to the respective movie studios. Based on the AUSOC Code of Best Practices, this qualifies as ‘Fair Use’ under US law, since we are “quoting in order to recombine elements to make a new work that depends for its meaning on [often unlikely] relationships between the elements”.
